Custom Plastic Extrusion: Definition And Materials

Today, plastic often seems to rule the world of consumer-oriented products. It makes its presence felt in everything from drinking straws to medical tubing. Many products are standardized. However, it is possible for companies, particularly in such specialized industries as medical equipment, to request the production of a unique part. The process of custom plastic extrusion makes their desire a reality.

What Is Plastic Extrusion?

Plastic extrusion is the process of using melted thermoplastic. The operative then forces it through a specific size and style die. The result is a solid shape featuring a fixed cross-section. This process is capable of manufacturing thousands of products daily. Customized adaptions of this form do not alter the basic process. Instead, the company performing this particular procedure customizes the die to produce the result desired by the customer.


The plastics employed in custom plastic extrusion – or any form of plastic extrusion for that matter, must fall into the category of thermoplastics. Only this type of polymer can successfully undergo melting and re-solidification. Among the plastics a company may utilize for customized plastic extrusion are:

• ABS (Acrylonitrile Butadiene Styrene)
• CPVC (Chlorinated Polyvinyl Chloride)
• PVC (Polyvinyl Chloride)- flexible/rigid/semi-rigid
• Polyethylene – High, Low or Linear Low Density (HDPE, LDPE, LLDPE)
• Polypropylene (PP)
• Polystyrene (HIPS)
• Polyurethane (PU)
• Santoprene
• Engineered Thermoplastics

New material is common, but customers can also request recycled plastics. However, whatever the nature, new or recycled, custom or standard, the plastics a plastic extrusion company will always select the material according to the requirements and specifications of the customer, e.g., chemical resistance, cost, dimensional stability, durability, pressure, environment.

Custom Plastic Extrusion

While some companies are content with standardized plastic products, others require customization. Custom plastic extrusion addresses the specifications of a customer for a component. Using new or recycled material, thermoplastics of a commercial or engineering grade, a plastic molding company can adhere to the exacting demands of a company, creating for them a unique component.
